Problems solved by technology
Because the element diameter is much larger than that of the coaxial line, the design can provide a wider operating bandwidth, but at the cost of a complex structure
[0005] Therefore, the commonly used collinear antenna array has complex structure, narrow bandwidth, long length, unstable antenna gain and radiation pattern, prone to problems of mechanical stability and manufacturability, and cannot adapt to different application scenarios.

The embodiment of the invention discloses a collinear antenna assembly and a series-fed omnidirectional collinear antenna array. The collinear antenna assembly comprises multiple series phase retarders. An antenna radiation unit is connected on the end part of each phase retarder. Each phase retarder comprises a circuit line printed on a dielectric plate. The antenna radiation unit is connected onthe two ends of the circuit line. The line length and the line width and the line spacing of the circuit line are set based on the preset wiring rule. The line length and the line width and the linespacing of the circuit line of each phase retarder are different based on different preset wiring rules so that the phase and the amplitude fed to each antenna radiation unit are precisely controlled,the maximum radiation efficiency of each antenna radiation unit is effectively controlled, the gain and the total radiation efficiency of the antenna array are improved, the sidelobe amplitude of theantenna array is reduced and the stable radiation downdip angle is obtained, thereby adapting to different application scenes.
Description
technical field [0001] The invention relates to the technical field of high-frequency antenna arrays, in particular to a collinear antenna assembly and a series-fed omnidirectional collinear antenna array. Background technique [0002] With the rapid growth of wireless communication systems, the demand for collinear antennas with high-performance horizontal omnidirectional radiation patterns is increasing. Due to its relatively simple structure and low production cost, series-fed omnidirectional collinear antenna arrays are widely used in modern wireless communication systems. [0003] A typical implementation of an omnidirectional collinear antenna array is realized by translocation interconnection of coaxial line segments. These arrays function by directing energy into the non-radiating section of the coaxial line during the half cycle, and the exposed section radiating during the positive half cycle, ensuring that the collinear antennas radiate only during the positive h...
